2. Description of the Related Art Conventionally, shampoos and body shampoos,
For detergents such as facial cleansers, coconut oil fatty acid diethanolamide and isopropanol laurate are combined with detergent bases such as anionic surfactants and amphoteric surfactants for the purpose of foaming, foam quality control and thickening. Linear fatty acid alkanolamides such as amides and lauric acid monoethanolamide are widely used.

However, when a washing base is combined with lauric acid monoisopropanolamide or lauric acid monoethanolamide, crystals may be precipitated at a low temperature, and when coconut oil fatty acid diethanolamide or the like is used. In many cases, sufficient foaming and detergency could not be obtained when used in a body or hair containing a large amount of sebum.
